Way further Left than Schwarzenegger are real Leftists, true Leninists. They intend to make life in this country so bad, so desperate, so hungry and unemployed, and the people so stupid, that the Leninist's lies about the "rich", "capitalist", "establishment", "souless corporations", etc. are believed by the "proletariat" to be the truth, and the Leninists will gain power and be able to hold it. Blood, blood, and more blood will keep them in power. The "McClintock" faction is furthering this "inner Party" Leftist agenda.

You are so right. What is even worse, they are doing it consciously -- some have stated that they actually prefer Bustamante to Arnold, and among the "some" McC is included, he stated that as well. Now what kind of Republican is someone who prefers "Bustamante, an Aztlan nationalist socialist, a racial purity fascist" (as you aptly put it), than to have a Republican win.
